Pressure transmitter for marine applications
Type MBS 5100 and MBS 5150
IC.PD.P20.T9.02 | 520B7974 | 1
The ship approved high accuracy block pressure
transmitter is designed for use in almost all
marine applications. MBS 5150 with integrated
pulse snubber is designed for use in marine
applications with severe medium influences like
cavitation, liquid hammer or pressure peaks and
offers a reliable pressure measurement, even
under harsh environmental conditions.
The transmitters can be easily mounted directly
on the MBV 5000 block test valve or the threaded
pressure connection can be used.
The flexible pressure transmitter programme
covers a 4 – 20 mA output signal, absolute
or gauge (relative) versions, measuring ranges
from 0 – 1 to 0 – 600 bar with zero and
span adjustment.
Excellent vibration stability, robust construction,
and a high degree of EMC / EMI protection equip
the pressure transmitter to meet the most
stringent industrial requirements.

Application and media
conditions for MBS 5150
Technical data
Application
Cavitation, liquid hammer and pressure peaks may occur in
hydraulic systems with changes in flow velocity, e.g. fast closing
of a valve or pump starts and stops.
The problem may occur on the inlet and outlet side, even at
rather low operating pressures.
Media condition
Clogging of the nozzle may occur in liquids containing
particles. Mounting the transmitter in an upright position
minimizes the risk of clogging, because the flow in the
nozzle is limited to the start-up period until the dead volume
behind the nozzle orifice is filled.
The media viscosity has only little effect on the response
time. Even at a viscosities up to 100 cSt, the response time
will not exceed 4 ms.
